Well if you mean by the master server, our beryllium server is closed, no it's not, we had some problems this past week with it but the issue has been fixed, the server is back up running smooth has before.
If you mean by the game itself well that is a problem with all the Quakes, i believe at some point you can't see the server list in your game itself.
This can be resolved by you typing the following commands in your console.
If you want to connect to our Beryllium server, all you need to do is /connect 18.104.22.168 and if you want to connect to our NoGhost you can by doing this /connect 22.214.171.124
I hope this helps!
